A Death in Diamonds

I enjoyed this more than the previous three, even though it's sad to lose Rosie. I think S.J.Bennett is just getting better at her job.  I thought the atmosphere of the 1950's was convincingly recreated, with genuine historical events skilfully scattered through the plot. If I have a criticism, it is that the solution is a bit too much of a surprise. Thinking back, there were clues there, however, and one really strong hint, which I failed to take heed of. I'm looking forward to the next one very much.
